Elastomeric Bridge Bearing Pad marketed by us, act as a buffer between the individual concrete members, preventing damage and allowing for easier movement. Bridge bearing pad provide for controlled movement, such as that caused by thermal expansion and contraction, while reducing stress. This pad is very effective and safe to use. Elastomeric Bridge Bearing Pad help isolate and soften the impact, shock, and vibration that occurs when the bridge is loaded vertically. This pad is very vulcanized to the rubber and have the primary purpose of increasing the bearings' resistance to vertical stresses.
